Just yesterday, we first heard word that Motorola may be launching versions of the XOOM (and the Atrix) on Sprint's network next month. Today it looks even more probable, as an image of a Sprint-branded XOOM has been posted by SprintUsers forum member r0fl.
The tablet looks identical to the Verizon model, aside from a Sprint logo. While something like this could easily be Photoshopped, keep in mind that the poster of the image "has a proven track record when it comes to unreleased Sprint hardware," according to BGR.
As we had not even heard wind of this two days ago, nothing else is known at this point. One can speculate whether it will tote WiMax capabilities or not (we are guessing so) and whether Sprint will offer a more competitive price than Verizon's $600 on-contract/$800 off-contract (we're guessing not at first), but it would all be just that: guesswork.
